11. Refill with the specified amount of the recom-
mended engine oil, and then insert the dip-
stick completely into the oil filler hole.
TIPBe sure to wipe off spilled oil on any parts after the
engine and exhaust system have cooled down. NOTICEECB00301In order to prevent clutch slippage (since the
engine oil also lubricates the clutch), do not
mix any chemical additives. Do not use oils
with a diesel specification of “CD” or oils of
a higher quality than specified. In addition,
do not use oils labeled “ENERGY CONSERV-
ING II” or higher. 
Make sure that no foreign material enters the
crankcase.
12. Start the engine, and then let it idle for several
minutes while checking it for oil leakage. If oil
is leaking, immediately turn the engine off and
check for the cause.
13. Turn the engine off, wait at least ten minutes, and then check the oil level and correct it if
necessary.
14. Install the access cover by turning it clock- wise.EBU27307Final gear oilThe final gear case must be checked for oil leak-
age before each ride. If any leakage is found, have
a Yamaha dealer check and repair the ATV. In ad-
dition, the final gear oil level must be checked and
the oil changed as follows at the intervals speci-
fied in the periodic maintenance and lubrication
chart.
To check the final gear oil level1. Place the ATV on a level surface.
Recommended oil:
See page 10-1.
Oil quantity: Without oil filter cartridge replacement:2.00 L (2.11 US qt, 1.76 Imp.qt)
With oil filter cartridge replacement: 2.10 L (2.22 US qt, 1.85 Imp.qt)

86. Check the oil filler bolt gasket for damage,
and replace it if necessary.
7. Install the oil filler bolt and its gasket, and then tighten the bolt to the specified torque.
8. Check the differential gear case for oil leak- age. If oil is leaking, check for the cause.
EBU23471CoolantThe coolant level should be checked before each
ride. In addition, the coolant must be changed at
the intervals specified in the periodic maintenance
and lubrication chart.EBU27129To check the coolant level1. Place the ATV on a level surface.
TIPThe coolant level must be checked on a cold en-
gine since the level varies with engine tempera-
ture. 2. Check the coolant level in the coolant reser- voir.TIPThe coolant should be between the minimum and
maximum level marks.
Recommended differential gear oil:See page 10-1.
Tightening torque: Differential gear oil filler bolt:23 Nm (2.3 m·kgf, 17 ft·lbf)

3. If the coolant is at or below the minimum level
mark, remove panel D to access the coolant
reservoir. (See page 8-10.)
4. Remove the coolant reservoir cap, add cool- ant or distilled water to the maximum level
mark, install the reservoir cap, and then install
the panel. NOTICE: If coolant is not avail-
able, use distilled water or soft tap water
instead. Do not use hard water or salt wa-
ter since they are harmful to the engine. If
water has been used instead of coolant,
replace it with coolant as soon as possible,
otherwise the cooling system will not be
protected against frost and corrosion. If
water has been added to the coolant, have
a Yamaha dealer check the antifreeze con-
tent of the coolant as soon as possible,
otherwise the effectiveness of the coolant
will be reduced.
[ECB01012]
TIP The radiator fan is automatically switched on or
off according to the coolant temperature in the
radiator.

WARNING
EWB01891Wait for the engine and radiator to cool before
removing the radiator cap. You could be
burned by hot fluid and steam blown out under
pressure. Always place a thick rag over the cap
when opening. Allow any remaining pressure
to escape before completely removing the cap. 1. Place the ATV on a level surface.
2. Remove panel D. (See page 8-10.)
3. Remove the footboard by removing the boltsand nuts. 4. Place a container under the engine, and then
remove the coolant drain bolt and its gasket.
(Use a trough or a similar object as shown to
prevent coolant from spilling on the engine
guard.)

89. After draining the coolant, thoroughly flush
the cooling system with clean tap water.
10. Install the coolant drain bolt and its new gas- ket, and then tighten the bolt to the specified
torque.
11. Connect the coolant reservoir hose.
12. Pour the recommended coolant into the radi- ator until it is full. 13. Pour the recommended coolant into the res-
ervoir to the maximum level mark, and then
install the reservoir cap. NOTICE: Mix anti-
freeze with distilled water only. However, if
distilled water is not available, soft water
may be used for refilling. Do not use hard
water or salt water since they are harmful
to the engine.
[ECB00992]
14. Loosen the water pump air bleed bolt, with- out removing it, to allow all of the air to es-
cape from the air bleed bolt hole.

819. When coolant begins to flow out of the bolt
hole, tighten the cylinder head air bleed bolt
to the specified torque.
20. Start the engine and let it idle for ten minutes.
21. Rev the engine five times.
22. Pour additional coolant into the radiator until it is full. 23. Stop the engine and allow it to cool. If the
coolant level has dropped after the engine
has cooled, add sufficient coolant until it
reaches the top of the radiator, and then in-
stall the radiator cap.
24. Start the engine, and then check for coolant leakage.
TIPIf any leakage is found, have a Yamaha dealer
check the cooling system. 25. Install the V-belt cooling duct, and then tight-en the clamp screw.
26. Install the footboard by installing the bolts and nuts, and then tighten them to the speci-
fied torques.

86. Wash the sponge material gently, but thor-
oughly, in solvent. WARNING! Always use
parts cleaning solvent to clean the sponge
material. Never use low-flash-point sol-
vents or gasoline to clean the sponge ma-
terial because the engine could catch fire
or explode.
[EWB01942]
7. Squeeze the excess solvent out of the sponge material and let it dry. NOTICE: Do
not twist the sponge material when
squeezing it.
[ECB00442]
8. Check the sponge material and replace it if damaged.
9. Apply Yamaha foam air filter oil or other qual- ity foam air filter oil to the sponge material.
TIPThe sponge material should be wet but not drip-
ping. 10. Install the mesh and the sponge material into the air filter case. NOTICE: Make sure that
the air filter element is properly seated in
the air filter case. Never operate the en-
gine with the air filter element removed.
Doing so would allow unfiltered air to enter
the engine, causing rapid engine wear and
possible engine damage. Additionally, the
fuel injection system would be affected re-
sulting in poor engine performance and
possible overheating.
[ECB00763]
11. Insert the projections on the air filter case cover into the holders on the air filter case,
and then install the air filter case cover by
hooking the holders onto the cover.

12. Place the hoses in their original position as
shown. 13. Install the panel.
TIPThe air filter element should be cleaned every 20–
40 hours. It should be cleaned and lubricated
more often if the ATV is operated in extremely
dusty areas. Each time the air filter element main-
tenance is performed, check the air inlet of the air
filter case for obstructions. Check the air filter
case rubber joint to the throttle body and the rub-
ber joint manifold fittings for an air-tight seal.
Tighten all fittings securely to avoid the possibility
of unfiltered air entering the engine. EBU28904Cleaning the spark arresterBe sure the exhaust pipe and muffler are cool be-
fore cleaning the spark arrester.

WARNING
EWB02341Do not start the engine when cleaning the
spark arrester, otherwise it could cause injury
to the eyes, burns, carbon monoxide poison-
ing, possibly leading to death, and start a fire.
Always let the exhaust system cool prior to
touching exhaust components. EBU23932V-belt case drain plugAfter riding in water deep enough to allow it to en-
ter the V-belt case, remove the V-belt case drain
plug to drain the water from the case.TIPIf water drains from the V-belt case after removing
the plug, have a Yamaha dealer check the ATV as
the water may affect other engine parts.
EBU29703Adjusting the throttle lever free playThe throttle lever free play should be checked and,
if necessary, adjusted at the intervals specified in
the periodic maintenance and lubrication chart.
The throttle lever free play should measure 3.0–5.0
mm (0.12–0.20 in) as shown. Periodically check
the throttle lever free play and, if necessary, adjust
it as follows.1. Slide the rubber cover back.
2. Loosen the locknut.1. V-belt case drain plug
